1. Do external metrics accurately predict internal adductor diameter?
2. Does adductor diameter change as the scallop matures?

Collected data from our three grow out sites (Neah Bay, Dabob Bay, and Totten Inlet)

scallop <- read.csv("Rdataformat_03132018.csv") %>% 
  select(Location, sex, mc_1_mode, T2_adductor) %>% 
  setnames(old=c("T2_adductor","mc_1_mode", "sex"), new=c("Adductor   Diameter (mm)", "Maturation Stage", "Sex"))

Gonad tissue samples were collected and histology slides were prepared to rate maturation stages of each individual scallop.

24 acini were rated for each individual and the mode across all 24 acini determined overall maturation stage for the organism.

• External metrics were significant (p-value<0.001) in determining internal adductor diameter.
• Correlation values 0.59-0.6

There was no significant relatioship between adductor diameter and gonad maturation stage.
